Interpret an engineering drawing
There is not a lot of space on a drawing so symbols and abbreviations are used instead of text. To find the meaning of a symbol or abbreviation, use the Australian Standard AS 1100.101-1992. It defines the general principles for technical drawing and shows tables of symbols and abbreviations and their meanings. Lines on a drawing also must conform to rules, eg, for visible outlines, hidden outlines, and dimension lines.
Creacion/Creatividad: Evaluando Dise?os Arquitect?nicos con Realidad Virtual (Creation/Creativity: E
?Can the computer improves the architectural creativity? This question is explored through a Virtual-Reality system developed for the modeling of timber structures, based on parametric elements, constructive programming and immersive visualization on real-time. Making experiences of evaluation with advanced students of architecture, whose use the system in the beginning of projects, compared with other group use not the system. This research faces the possibilities to rationalizate part of the c
1.9 Distance between points in three-dimensional Euclidean space
Attempts to answer problems in areas as diverse as science, technology and economics involve solving simultaneous linear equations. In this unit we look at some of the equations that represent points, lines and planes in mathematics. We explore concepts such as Euclidean space, vectors, dot products and conics.

Women in Maths - Lisa Mott
In August 2014 Maryam Mirzakhani, a professor at Stanford University, became the first woman to win the Fields Medal for achievements in mathematics, a medal comparable in prestige to a Nobel Prize, first awarded in 1936. Although around 40% of the UK undergraduates in mathematics are women, there is a well-documented leaking pipeline when it comes to women choosing to do a PhD and then choosing an academic career path. The proportion of women mathematicians declines rapidly the higher one loo
In this interactive activity adapted from Wake Forest University, learn about torque. Observe the rotational motion of a beam pivoting about a central axis and see how a mass's horizontal distance from the pivot point determines the rotational force it exerts. Watch as masses are added to either side of the beam at various distances to create different amounts of torque, and see how a variety of combinations can be used to reach equilibrium. In addition, see how it becomes easier to loosen a bol
How Wind Power is Converted into Useful Electrical Energy
This video provides a brief tutorial - about harnessing wind energy. The high quality animation is supplemented with text - which explains how wind power - is converted to electrical energy, via a generator. Computer animation set to music with labels provided on screen. (No narration) Run time 02:10.
This is a module framework. It can be viewed online or downloaded as a zip file. As taught Autumn semester 2009 Infections are a major cause of morbidity and mortality worldwide. The body fights infection through the functions of the immune system, whose power has been harnessed by the development of vaccination (immunisation). Suitable for study at: Undergraduate levels 1 and 2. Dr Ian Todd, School of Molecular Medical Sciences Dr Ian Todd is Associate Professor & Reader in Cellular Immunopatho
Saft says: Tale of the whale also about too big to fail
Jan. 17 - Reuters Columnist James Saft says banks will remain susceptible to speculative dangers as long as they're too big to fail.
Beyond Witness: New Approaches to Crisis Photography (Introduction)
http://pulitzercenter.org/blog/videos-beyond-witness-new-approaches-crisis-photography-fotoweek We live in an era saturated with images of all kinds clamoring for our attention. Combine this with constantly shrinking space for serious, thought-provoking photography on complex issues, and a clear problem emerges. As a result, photojournalists must explore new ways to tell stories and identify or create new outlets for such work to be seen. Pulitzer Center photographers Dominic Bracco II, Sean G
Experiments as Modus Operandi
Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provok
Introduction to Philosophy II
This course is designed as a "topics-based" introduction to philosophy. What this means is that instead of working through the history of philosophy focusing on great historical figures and their views on different topics, we will focus on great philosophical topics and look at what historical and contemporary writers have said about them. Topics to be addressed will include the existence of God, the relation between the mind and the body, human freedom, and the foundations of morality.
Painting with Negative Space and Silhouettes
Here's another technique. A great number of people find it easier to see or find images in shapes rather than from lines. When drawing from line the mind often gets caught up in symbols, whereas when focusing on contour or silhouettes it does not. For this reason it's worthwhile to paint the space around a person or object. (6:36)

This lecture constitutes an introduction to creep and to the creep response of aluminium and its alloys. It provides basic information on creep and its mechanisms; it gives a description of the more extensively used mathematical relations among creep variables (time, stress and temperature); it illustrates the creep response of pure Aluminium and of Al-Mg alloys; it provides a synthesis of the information available in the literature on the creep behaviour of a number of new alloys and composites
